The paper discusses water–rock interaction in areas where wastes of tungsten ore processing are stored, as exemplified by the Dzhida and Bom-Gorkhon mining and processing complexes. Pore waters at the tailing dumps become acidic, and the solutions are enriched in decomposition products of the sulfide minerals and rocks. When the wastes are stored for a long enough time, interaction between the acidic solutions and rocks hosting ore mineralization leads to water enrichment in HREE. The paper presents data on the neutralizing properties of limestone. REE are demonstrated to be able to enrich interaction products of the acidic waters and limestone in the form of newly produced amorphous mineral phases.

俄罗斯外贝加尔地区钨矿开采企业地表水和地下水中的稀土元素

该论文讨论了储存钨矿石加工废料的地区的水-岩相互作用，例如 Dzhida 和 Bom-Gorkhon 采矿和加工综合体。尾矿场的孔隙水变成酸性，溶液富含硫化物矿物和岩石的分解产物。当废物储存足够长的时间时，酸性溶液和承载矿石成矿的岩石之间的相互作用导致重稀土中的水富集。该论文提供了有关石灰石中和特性的数据。REE 被证明能够以新产生的无定形矿物相的形式丰富酸性水和石灰石的相互作用产物。
